I actually manage servers and network services, and am familiar with the importance of five nines uptime. It seems like this kind of an interface is a failure in that it provides quick information to most people but doesn’t include information for people with disabilities. I think it would be beneficial to have that visual interface with color information but to also include information that showed bars of different heights and widths.

I understand that the direct inclusion of all of the numbers could clutter the interface and make it less easy to immediately tell uptime, but even without the numbers it seems that significant improvements could be made to the way this information is presented with this layout.
